'lo (dt Ilelie/'rt it muy concer-n.'

Bc it known that I, WILLIAM G. TEMPLE- TON, a citizen ofthe United States, residing at Colorado Springs, in the county of El Paso and State of Colorado, have invented a new and useful Ieighing-Scale, of which the followingr is a specification. Y

This invention relates to weighing scales, and has for its principal object to provide a novel form of scale in which )revision is niade for correctly indicating different weights and for calculating the values of materials weighed, the scale being so arranged that a very large number of unit values may be employed. A

A further object of the invention is to provide a scale of lsimple plural indicating means is om loycd for the pui-posse of' increasing tbe num )er of rate and valu(` tables, or for the purpose of indicating weights and vahies in accordance with different `standards, as, for instance, a scale for druggists use may be made to indicate weights in. accordance with apotheca'ries, troy, or avoirdu )ois standards, and one set of tables may, if i nection with tables indicating rates of postage.

A still further object of the invention is t0 )rovide a. scale having an indicating disk )caring a plurality of separate indicating tables which are arranged to be viewed through a corresponding number of openings formed in the casing of the scale, there being a read ing edge or wire at each opening, so that the weights or values at different points may be correctly ascertained.

A still further object of the invention is to provide a novel form of scale in which the indicating disk is carried by or is o erated from a counter-poise in the forni o a segment, the segment servin(7 to resist the downward movement of the oad recciveriunder .the weight of a load and the counter-balancing effect being to some an auxiliary weight or counter-poise.

With these and otherobjects in view, as will more fully hereinafter appear, the invention consists in construction and arrangement of parts, hereinafter full)Y described, illustrated in the accompanying drawings, and particularly pointed out in the appended claims, it being 1im'ler-stan.' itx-:it sfr-:riens i 22.-. .i n proportions, size and minor details of the structure may bc made without departing construction in whichaf .intermediate casing 13, all

'constructed and arranged in any suitable esired, beeinployed in con-i extent opposed by certain novel features of s in the forni,

from the s irit or sacrificing any of the advanta res o the invention. f

In t ie accom anying drawingsz`Figure 1 is a sectional c evation of a weighing scale constructed in accordance with the invention. Fig. 2 is a vertical section of thc'interior of the scale showin the counter-poise in a different position. ig. 3 is a transverse sectional view on an enlarged scale of the indicating mechanism, lFig- 4 is a sectional elevation, -illustratinvr a modification. f

Similar numerals of reference are employed to indicate corresponding parts throughout the several figures of the drawings.

The frame of the scale includes a base 10, a column 11, a circular easing 12, and an of which may be manner.

`In the present instance the load receiving platform 15 is carried byavertically arranged rod 16 that is supported by a frame 17, the rear end of which is permanently secured to the lower end :of the tension or sus iension rod 18 which connects with the in( icatingr mechanism.' In order to prevent swaying of the latform during the wei Vlun movement,

the ower forward ortiono the rame is )rovided with knifi'ei edge 20 between which and a rigid knife edge 21 is arranged a link structure 22 which is subjected to compression strain during the weighing operation, and which serves to hold the platform from lateral sway while in operation.

. In the intermediate casing 13 iii-arranged a parallel motion device 24 which maybe of any suitable constructioi'i and is employed for the purpose, of maintaining the suspension rod 18 in a vertical plane.

The u per casing 12 includes. a `air of 'circular disks 3() the central rn'n'tions olivhich are'secured to a drinn 34 which may be of' any desired construction, and this drinn is arranged to be revolved fi'oni the sus )cnsion rod in any suitable manner. In the prefel-red construction a flexible member 35 that may be in the forni of a chain, cord, or strap is attached at one end to the drum and is wound partly around the same, and its op )osite end is connected to the suspension rod 18 ofthe scale, so that any downward movementof the suspension rod will serve to tra isint rotative movement to the drinn.

'.'i'ie downvf'ard moyennant of the suspension rod 18 under the influence of its own weight added to that of the platform and the u"`froiii`the axis of the drum and dials.

` 60 with dilfercnt scales, as, fer instance, apotheother associated parts of the scale is counter# balanced, or more than counter-balanced by a wei lit 438 that' is connected by a pair of exib e mcmbeis 39 to the drum, these mem- 5 bers being wound around the drum as the member is unwound therefrom, and vice versa.

The countenpoise in the present instance is in the form of a segment or segments 40 10 which are preferably formed of metal and are rigidly secured to the opposite ends of the drum. Tlieseseginents are ap )roximately inl the form of quadrants and` wlien there is no load on the ilatform the segments normally assume the positions shown in Fig. 2, so that the greater wei lit of the segment is thrown to the rightof.t ie vertical plane ofl the axis of the drum, and the weight of the segment therefore tends to force the load receiver downward, but this downward movement is prevented and a state of equilibrium is established by the counter-weight 3S before described. l Y

The effect of throwing the whole of the counter-poise to the right is to increase the capacit' of thescale beyond that which it would iave if the center of gravity of the counter-poise were allowed to normally 1'e, main in the vertical plane of theaxis of the drum. l

In s oiue cases the auxiliary counter-weight may be of the construction shown in Fi 4, wherein the weight 38 is in the form o an inverted cylinder which fits over a stationary piston carried by a part of the frame and constitutes a small dash-pot which will prei vent abi'u t movement of the load receiver -in either irection.

Secured to the segments are indicating dials 50, there being two of such indicating dials shown in the present instance in connection. with the two segmental c0unterweights, althouvh only a. single counter- -weight and sing e dialmay be used in some cases.

Innsniuch as the full extent of weighing movement of the dial is limited to a quarter of ii revolution iii the present instance, each dial is r vided with four different sets of weight in@ icating graduations which are exposed at four differentdisplay openings 52, and across these openiii s extend reading wires 53 that are arrange on lines radiating As the 55 weiglit""indicating graduations of the dial move past these reading edges the correct weight ma 'be read at any\o e four ointsfan advantage maybe taken of`tlis y making the graduations in accordance caries, troy or avoirdulp ois. I One of the principe advantages to be derived from the plurality ci indicating points, l

however, is that it permits of the employment of the scale as a calculating device of much wider ran e than scales which have only a single in icator, it being possible to" employ about four times the number 4of unitary values oppositethe dial and acorren spondin ly increased number- `of total valuesV 701 on the ial proper at points in radial alinement with the weight indicating aduatios. While the counterpoise and ial carrying member has been termed a, drum for convenience, it is to be understood that a shaft, spindle, or other equivalent rotatable niember may be substituted therefor without departing from the invention.

I claim 1. In a weighing scale, a drum, a load`re- 8o ceiver, a flexible member havin one end connected to the load receiver, an the opposite end to the drum, a segmental counterpoise carried by the drum an auxiliary couii-` f tepweight also connected to the drum and 86 tending to resist downward movementof the Joad receiver, a dial member carried bythe segmental-counter oise and rovided with aplurality of setso weight in icating graduf ations, and a cover or casing 'Within which 90 th'dial member is located, said cover or casing havinga luralitof radially arranged r openings throng wliic the graduations are '1 independently exposed. 2. In a weighing scale, a revolubleruni, a load-receiver having a flexible connection therewith, a counter-Weight tendin tore,- sist downward movement of the oad re ceiver, said counter-weight having a flcxi ble connection with. the drum, a s mental counter-poise carried by the drum, t e canter of ravity of the counter-poise being normally ield to one side of the vertical plane -of the drum axis by the counterwe` ht, and

a graduated dial revoluble with the rum.

3. -In a weighing scale, a revoluble drum, a load receiver having a flexible connection with the drum, a segmental counter-poise l connected to the drum an auxiliary counter` weight having a ilexibl drum and acting to resist downward movement of the load receiver and to normally y maintain the center'ofgravity of the counl ter-poise to one side of the vertical plane ofi the axis of the drum, and an indicating dial 11tsecured to andmovable with the se ment f said dial being provided'with a plur 'ty o sets of weight indicatin raduatlons.

In testimony that 1 c aim the foregoing as my own, I have hereto aixed my signature in thepresence of two witnesses.
